Watch: The many questions raised by the failed execution of Christa Pike

The execution of convicted murderer Christa Pike in Tennessee was halted after she remained conscious following the administration of lethal drugs. Her legal team filed an emergency motion as medical staff attempted life-saving measures.
Why it matters
The incident raises significant ethical and legal questions regarding the efficacy and humaneness of current lethal injection protocols in the United States.
Her legal team filed an emergency motion to halt the convicted murderer's execution as it was happening, saying: "Ms Pike has lost consciousness and still has a heartbeat and is audibly snoring."
One of her attorneys told the BBC that Pike, 50, was "being provided life-saving measures" in hospital after two syringes of pentobarbital had been administered on Wednesday.
Pike was sentenced to death in 1996 for the murder of 19-year-old Colleen Slemmer.
